Expert Advisor Upgrade

What I would like to do is add some modifications to my current EA. These modifications include turning the mandatory moving average crossovers into a true/false statement. I would also like to include a new price action filter. This would entail using the previous days Open and close to determine if the current days price is within a buy zone or sell zone. Another development I would like is for the RSI to also determine when to move the stops up. Lastly, I would like an option to have the stop moved with the crossover on the RSI.
